Abstract: We propose the use of a tight frame expansion for generalized multiple description coding. This method is conceptually very similar to using a block channel code, except it is done on continuousvalued data prior to quantization. A sketch of the distortion analysis is given. I. Introduction Recently the problem of transmitting data over heterogenous networks has received considerable attention. A typical scenario might require data to move from a fiber link to a wireless link, which... (Update)
